[0002] In the film processing industry, film cutting machines are one of the most commonly used pieces of equipment. During the film cutting process, the film needs to be effectively fixed to ensure cutting accuracy and quality.

[0003] Currently, traditional film cutting machines typically use simple fixed pressure rollers to fix the film. However, fixed pressure rollers cannot flexibly adjust the pressing force according to the thickness of the film, which can easily lead to uneven force on the film, resulting in wrinkles, damage, and other issues, thus affecting the cutting effect of the film. Therefore, we need to propose a pressing roller assembly and a film cutting machine. Utility Model Content

[0004] The purpose of this invention is to provide a pressing roller assembly and a film cutting machine. Through the adjustment mechanism and the setting of two sets of pressing rollers, the two sets of pressing rollers achieve bidirectional symmetrical pressing of the film, which effectively improves the stability of film pressing and fixing. The adjustment mechanism can synchronously and flexibly adjust the pressing force of the two sets of pressing rollers, so as to accurately adjust the pressing force of the two sets of pressing rollers according to different film thicknesses, thereby solving the problems mentioned in the background art.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: A press-type pressure roller 2 assembly includes: a support frame 1; two sets of pressure rollers 2 disposed inside the support frame 1; and an adjustment mechanism 3 for flexibly pressing and adjusting the two sets of pressure rollers 2, wherein the adjustment mechanism 3 is disposed on the top of the support frame 1.

[0020] With the support frame 1, two sets of pressure rollers 2, and adjustment mechanism 3, the two sets of pressure rollers 2 achieve bidirectional symmetrical pressing of the film, effectively improving the stability of film fixation. The adjustment mechanism 3 can flexibly adjust the pressing force of the two sets of pressure rollers 2 according to different film thicknesses, avoiding the film deformation problem caused by uneven pressure in traditional fixed pressure rollers 2. Therefore, the adjustment mechanism 3 not only enhances the adaptability of pressure rollers 2 to films of different thicknesses, but also significantly improves the stability of film fixation, ensuring that the film remains flat during cutting, thereby ensuring cutting accuracy and processing quality.

[0021] Furthermore, such as Figure 2-3 As shown, the adjustment mechanism 3 includes a motor 31, a threaded rod 32, a movable plate 33, multiple sets of pressure plates 34, and two sets of connecting frames 35. The motor 31 is fixedly installed on the top of the support frame 1, and the output end of the motor 31 is fixedly connected to the top of the threaded rod 32 through a coupling. The movable plate 33 is threadedly installed on the outside of the threaded rod 32. The two sets of pressure rollers 2 are respectively arranged inside the two sets of connecting frames 35, and the tops of the two sets of connecting frames 35 are symmetrically fixedly installed with pressure plates 34. The tops of the multiple sets of pressure plates 34 are all fixedly connected to the bottom of the movable plate 33.

[0022] With the configuration of motor 31, threaded rod 32, moving plate 33, multiple pressure plates 34 and two sets of connecting frames 35, motor 31 can be a Panasonic MINAS-A6 series servo motor. Starting motor 31 drives threaded rod 32 to rotate, thereby driving moving plate 33 to move vertically. Through pressure plates 34 and connecting frames 35, the two sets of pressure rollers 2 are adjusted synchronously to ensure that the pressing pressure is evenly transmitted to the film, effectively improving the stability and uniformity of film fixation, and avoiding the risk of wrinkles and damage to the film due to uneven force.

[0023] Specifically, such as Figure 3 As shown, two sets of sliders 4 are fixedly installed on both sides of the movable plate 33, and two sets of sliding grooves 5 are opened on both sides inside the support frame 1 for the sliders 4 to slide.

[0024] With the sliders 4 and grooves 5, the sliders 4 on both sides of the moving plate 33 slide in the grooves 5 on the support frame 1, which plays a dual role. On the one hand, the sliders 4 sliding in the grooves 5 provide precise guidance for the moving plate 33, ensuring that the moving plate 33 rises and falls smoothly in the vertical direction and avoiding uneven force on the pressure roller 2 due to deviation. On the other hand, the limiting function of the grooves 5 on the sliders 4 effectively prevents the moving plate 33 from shaking during the adjustment process, enhances the stability of the adjustment mechanism 3, makes the film fixing process more reliable, and further improves the film cutting accuracy.

[0025] Furthermore, such as Figure 3 As shown, a support plate 6 is fixedly installed inside the support frame 1, and the bottom end of the threaded rod 32 is rotatably installed on the top of the support plate 6.

[0026] By setting the support plate 6, the support plate 6 provides support to the bottom end of the threaded rod 32, dispersing the axial force borne by the threaded rod 32 during rotation, preventing it from bending or shaking due to uneven force, significantly enhancing the stability of the threaded rod 32 during rotation, preventing the shaking of the threaded rod 32 from affecting the pressure adjustment accuracy of the pressure roller 2, and ensuring the reliability of the entire adjustment mechanism 3.

[0027] In this embodiment, as Figure 2 As shown, the support plate 6 has multiple sets of through grooves 7 inside, and multiple sets of pressure plates 34 are slidably disposed in the multiple sets of through grooves 7.

[0028] By setting the through groove 7, the through groove 7 provides precise guidance for the lifting and lowering of the pressure plate 34, restricts the horizontal displacement of the pressure plate 34, and ensures that the pressure plate 34 drives the pressure roller 2 to press down vertically, so that the pressure roller 2 can evenly transmit the pressure to the film surface. In addition, the through groove 7 can also help the pressure plate 34 to disperse the pressure, avoid local stress concentration, further improve the uniformity of film fixation, and reduce the risk of film damage caused by sudden pressure changes.

[0029] Another aspect of this utility model provides a die-cutting machine, which also includes: Film cutter 8; lifting mechanism 9 for lifting and lowering the film cutter 8 for film cutting, and the lifting mechanism 9 is located at the bottom of the support plate 6.

[0030] With the combination of the film cutting blade 8 and the lifting mechanism 9, after the pressure roller 2 assembly fixes the film, the lifting mechanism 9 drives the film cutting blade 8 to move up and down, thereby realizing the integrated operation of film from fixing to cutting, and improving film cutting efficiency and quality.

[0031] Specifically, such as Figure 2 As shown, the lifting mechanism 9 includes a mounting frame 91, an electric push rod 92, and two sets of guide rods 93. The mounting frame 91 is fixedly installed at the bottom of the support plate 6, the electric push rod 92 is fixedly installed inside the mounting frame 91, and two sets of guide rods 93 are symmetrically fixedly installed on the top of the film cutting knife 8, and both sets of guide rods 93 are slidably arranged inside the support plate 6.

[0032] With the installation of the mounting bracket 91, electric push rod 92, and two sets of guide rods 93, the mounting bracket 91 provides a mounting base for electric propulsion, while the electric push rod 92 serves as the power source for the lifting mechanism 9, ensuring that the cutting blade 8 achieves stable and precise vertical lifting. The Thomson Electrak-HD series can be selected. The electric push rod 92 drives the cutting blade 8 to lift and lower stably along the guide rod 93, and the guide rod 93 provides guidance for the cutting blade 8, ensuring a smooth and vertical cutting process, preventing the cutting blade 8 from deviating, and ensuring cutting accuracy and cut quality.

[0033] Furthermore, such as Figure 4 As shown, the movable plate 33 has through slots 10 on both sides for the guide rod 93 to move through, and the through slots 10 are located between the two sets of sliders 4.

[0034] By setting the through slot 10, the guide rod 93 can pass through the through slot 10 on the moving plate 33 freely, avoiding interference between the cutting blade 8 and the moving plate 33 when it is raised and lowered. This ensures that the pressure roller 2 adjustment mechanism 3 and the cutting blade 8 lifting mechanism 9 do not affect each other, and achieve stable and coordinated operation of the two. This not only ensures the smooth operation of the equipment, but also makes the film fixing and cutting process seamlessly connected, improving the overall stability and reliability of the equipment.

[0035] It is worth mentioning that, such as Figure 1 As shown, the two sets of pressure rollers 2 are located on both sides of the cutting blade 8.

[0036] By symmetrically positioning the pressure rollers 2 on both sides of the film cutting blade 8, the film remains stable during cutting, effectively preventing displacement or deformation of the film during the cutting process, thereby improving the cutting accuracy and finished product quality.

[0037] Furthermore, such as Figure 2 As shown, a base plate 11 is fixedly installed at the bottom of the support frame 1, and a cutting groove 12 is provided on the top of the base plate 11.

[0038] The base plate 11 and the cutting groove 12 provide a cutting space and support surface for the film cutting knife 8, making it easy for the film cutting knife 8 to penetrate the film and complete the cutting. When the film cutting knife 8 descends to cut, the blade of the film cutting knife 8 can smoothly enter the cutting groove 12, which not only avoids the film cutting knife 8 from colliding with the base plate 11, but also protects the cutting edge of the film cutting knife 8 from damage and extends its service life.

[0039] Working principle: When this utility model is in use, firstly, the film is placed between the pressure roller 2 and the base plate 11. Then, the motor 31 is started. The motor 31 drives the threaded rod 32 to rotate through the coupling. The rotation of the threaded rod 32 causes the threaded moving plate 33 to move vertically. The moving plate 33 is guided in the slide groove 5 of the support frame 1 by the sliders 4 on both sides to ensure smooth movement. The downward movement of the moving plate 33 pushes the two sets of connecting frames 35 simultaneously through multiple sets of fixedly connected pressure plates 34, which in turn drives the two sets of pressure rollers 2 to apply downward pressure. The pressure of the pressure rollers 2 can be precisely adjusted by controlling the rotation angle of the motor 31 to adapt to films of different thicknesses. The two sets of pressure rollers 2, after being adjusted, are located on both sides of the film cutter 8, forming symmetrical pressure on the passing film. Then, the electric push rod 92 in the mounting frame 91 is activated to push the film cutter 8 down for cutting. The sliding of the two sets of guide rods 93 in the support plate 6 ensures that the film cutter 8 moves vertically. The through groove 10 set on the moving plate 33 provides movement space for the guide rods 93. When the film cutter 8 moves down, its blade is aligned with the cutting groove 12 on the top of the base plate 11, thereby completing the precise cutting of the film. After the cutting is completed, the electric push rod 92 drives the film cutter 8 to reset, and the motor 31 reverses to raise the pressure rollers 2, making it easy to remove the film.
